MEMBERSHIP of political parties has decreased significantly since 1994 according to a survey by the Human Sciences Research Council (HSRC) in Pretoria. The slip is even more evident among African respondents where active membership of political parties decreased from its high of 24% in 1994, to 10% in 1999. In the same period active membership among white South Africans decreased from 17% in 1994 to 9% in 1999. While about one in five of the respondents in the survey were active members of a political party shortly before the 1994 election, this figure decreased overall to less than one in ten in November 1999, it was found.
